At the start of a motion along a line the initial velocity is u and acceleration is at. The final velocity v after time t, is

A

`v=u+at`

B

`v=u+at^(2)`

C

`v=u+(1)/(2)at^(2)`

D

`v=at^(2)`

Text Solution

Verified by Experts

The correct Answer is:
B
given, initial velocity, u=u
acceleration a=at
`therefore`Final velocity is `v=u+at=u+(at)xxt=u+at^(2)`.
